ABSTRACT:
A semiconductor memory uses cells with a ferroelectric capacitor having one plate coupled to a bit line by a FET and another plate coupled to a plate line. A pulse on the plate line causes the bit line to change voltage based on the state of the cell. A dummy cell arrangement is disclosed using one capacitor per cell, and another embodiment uses two capacitors per cell with no dummy. The cells cooperate with a sense amplifier and timing signals so that they are self restoring.
